     An advance system  700  comprises a sprocket  710  which is rotatable by the user&#39;s finger and a film counter  720  which rotates with the rotation of the sprocket. The film counter  720  located on the tip face of the body is a disc displaying the number of remaining pictures, on which additional notation “value” (referred to as AS) irrelevant to the number of the films is indicated. And the additional notation “value” is indicated in a counter window  725  at the time when the number of the remaining pictures becomes zero.

FIELD OF THE INVENTION

[0001] The present invention relates to a film unit with a lens.

DESCRIPTION OF RELATED ART

[0002] A film unit with a lens is widely used as a disposable camera.There are no goods or services that have added any purposes to the filmunit with a lens other than the purpose of taking a photo.

SUMMARY OF THE INVENTION

[0003] An objective of this invention is to provide same characteristicswith a film unit with a lens to give it an additional value as a toolfor providing various services.

[0004] A film unit with a lens in connection with this inventiondisplays an additional notation to a film counter, which gives the filmunit with a lens game characteristics. Thereby, various services arecapable of being provided in accordance with the additional notation.

[0005] In this invention, the additional notation indicates a service toa user of the film unit with a lens, and it may be a personalidentification number for the user receiving a prescribed service.

[0006] Moreover, a method for providing a service in connection withthis invention displays an additional notation to a film counter of afilm unit with a lens, and provides a prescribed service to a user inaccordance with the additional notation. Thereby, a film unit with alens that has been widely used can be employed as a tool for providingvarious services.

EMBODIMENTS

[0012] Next, described is one embodiment of a film unit with a lens inconnection with this invention according to the drawings.

[0013]FIG. 1 is a perspective view showing the face of a film unit witha lens. FIG. 2 is a perspective view showing the back of a film unitwith a lens. FIG. 3 is a partly breaking perspective view showing theback of the same embodiment. FIG. 4 is a perspective view showing anadvance system.

[0014] A film unit with a lens comprises an optical system 200, a flashlamp 300 and a flash lamp switch 400 on the face of a body 100, arelease switch 500 on the top face of the body 100, a finder 600 whichopens to the back and the face on the upper part of the body 100. In thefilm unit with a lens, a film with a film cassette (omit the drawing) isstored in advance, which is rolled up by an advance system 700.

[0015] As is well known, the body 100 holds the light density of thefilm, the optical system 200 focuses an image of an object onto thefilm, the flash lamp 300 emits the light to illuminate the object upontaking the photo, the flash lamp switch 400 starts the charge in orderto emit the light of the flash lamp 300, and the release switch 500starts the film exposure by the optical system.

[0016] The advance system 700 comprises a sprocket 710 which isrotatable by a user's finger, and a film counter 720 which rotates witha rotation of the sprocket. The film counter 720 is a disc whichdisplays the number of remaining pictures on the top face of the body,and when the sprocket 710 is made to be rotated rightward (the directionof arrow A in FIG. 4), the film counter 720 rotates leftward (thedirection of arrow B in FIG. 4). Any one of the numbers of the filmcounter 720 is displayed in a counter window 725 on the top face of thebody 100. Moreover, the number of taken pictures can also be displayedin the film counter 720. In this embodiment, in order to display thenumber of remaining pictures, the number that sequentially decreases tothe direction opposite to the direction B is displayed.

[0017] The sprocket 710 is connected with a gear 740 through a centralaxis 730, and the gear 740 is engaged with a gear 760 through the filmcounter 720 and a central axis 750. The film is rolled up by therotation of the central axis 730. The gear 740 is narrower than the gear760, and when the central axis 730 rolls up one frame of the film, thefilm counter 720 rotates to decrease by one the number of remainingpictures which are displayed in the film counter 720.

[0018] The gear 760 is engaged with a ratchet 780 energized by a spring770, and at every instance of the rolling up of one frame of the film,the advance system 700 goes off.

[0019] In the film counter 720, shown in FIG. 3 and FIG. 4, anadditional notation “value” (described in number AS) irrelevant to thenumber of pictures is displayed, and which is displayed in a counterwindow 725 at the time when the remaining number becomes zero. Theadditional notation AS is randomly set up in the film unit with a lens,and in accordance with the additional notation, the producers orproviders of the film unit with a lens may provide a user with variousservices. That is, the film unit with a lens can be employed as a toolfor providing various services.

[0020] Furthermore, as an additional notation, various notations may beselected to be displayed such as various giveaways or premiums that areto be the objects of the services, or various indications such asfortunetelling (excellent luck, good, LUCKY), colors or symbols, etc.The subject of services is not limited to the producer and the like ofthe film unit with a lens.

[0021] Moreover, it is possible to make the additional notation apersonal identification number, in accordance with which the serviceswill be provided. For example, as shown in FIG. 5, when a user US whoobtained a personal identification number PIN, such as a secret number,accesses a service provider PD through the internet IN, the servicescorresponding to the personal identification number may be provided.

[0022] As mentioned above, the film unit with a lens which is greatlyused can be employed as a tool for providing various services, andenables itself to be promoted, as well as is capable of being used as anew marketing tool, an advertising medium and digital money.
